Es ist eine mehrschichtige Kunststoffscheibe bekannt,
Aufgabe der Erfindung ist es eine Kunststoffglasscheibe zur Verfügung zu stellen, die eine erhöhte Verschleiß- und Medienbeständigkeit aufweist.The object of the invention is to provide a plastic glass pane that has increased wear and media resistance.
Die Lösung dieser Aufgabe ergibt sich in Verbindung mit den Merkmalen des Oberbegriffs des ersten Patentanspruchs erfindungsgemäß im Zusammenspiel mit den technischen Merkmalen dessen kennzeichnenden Teils dadurch, dass die Schutzschicht der Kunststoffglasscheibe aus einer flexiblen durchsichtigen Glasschicht auf mindestens einer ihrer beiden Oberflächen besteht.The solution to this problem results in connection with the features of the preamble of the first claim according to the invention in interaction with the technical features of its characterizing part in that the protective layer of the plastic glass pane consists of a flexible transparent glass layer on at least one of its two surfaces.
Dieses Glasschicht weist eine hohe Beständigkeit gegen aggressive Medien wie Putzmittel auf, ebenso wie gegen aggressive Gase und auch eine hohe Beständigkeit gegen eine Versprödung, so dass eine hohe Langzeitbeständigkeit der damit versehenen Kunststoffglasscheibe gewährleistet werden kann. Des Weiteren ist die Glasschicht äußerst verschleißbeständig gegen abrasive Medien, so dass die Durchsichtigkeit einer damit versehenen Kunststoffglasscheibe über eine lange Zeit ungetrübt erhalten bleibt.This glass layer has a high resistance to aggressive media such as cleaning agents, as well as to aggressive gases and also a high resistance to embrittlement, so that a high long-term stability of the plastic glass pane provided with it can be guaranteed. Furthermore, the glass layer is extremely wear-resistant against abrasive media, so that the transparency of a plastic glass pane provided with it remains undisturbed for a long time.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous configurations of the subject matter of the invention emerge with and in combination from the following subclaims.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist die Kunststoffglasscheibe als Hausfensterscheibe ausgebildet, wobei sie auch als Zwei- oder Mehrscheiben-Isolierglasscheibe mit dazwischen ausgebildeten Luft- oder Gasschichten ausgeführt sein kann, wobei die Glasschicht großflächig auf den jeweils außen liegenden Oberflächen aufgebracht ist. Solche Hausfensterscheiben weisen ein erheblich geringeres Eigengewicht auf als herkömmliche Glasscheiben, wobei die beidseitige Beschichtung mit einer Glasschicht dafür sorgt, dass der Umgang mit der erfinderischen Kunststoffglasscheiben der gleiche bleibt wie mit herkömmlichen Glasscheiben. Weiterhin lassen sich solche Hausfensterscheiben erheblich wirtschaftlicher herstellen als solche aus reinem Glas.According to a particularly preferred embodiment of the invention, the plastic glass pane is designed as a house window, it can also be designed as a double or multi-pane insulating glass pane with air or gas layers formed in between, the glass layer being applied over a large area to the outer surfaces. House window panes of this type have a significantly lower weight than conventional glass panes, the double-sided coating with a glass layer ensuring that the inventive plastic glass panes are handled the same as conventional glass panes. Furthermore, such house window panes can be manufactured considerably more economically than those made of pure glass.
Entsprechend einer anderen bevorzugten Ausgestaltung der Erfindung ist die Kunststoffglasscheibe als ebene oder gebogene Fahrzeugfront-, -seiten-, -heck- oder -panoramadachscheibe ausgebildet, wobei der Gewichtsvorteil der Kunststoffglasscheibe deutliche Vorteile mit sich bringt, ebenso wie einen hervorragenden Splitterschutz der Kunststoffglasscheibe, die aus Polycarbonat (PC) oder einem anderem transparenten Kunststoff, wie Polymethylmethacrylat (PMMA) oder Polyethylen (PE) bestehen kann, wobei die innen und außen aufgebrachten Glasschichten die Kunststoffglasscheibe bei der Benutzung von Scheibenwischern oder von aggressiven chemischen Reinigungsmitteln von der Innen- oder Außenseite eines Fahrzeugs her schützen.According to another preferred embodiment of the invention, the plastic glass pane is designed as a flat or curved vehicle front, side, rear or panoramic roof pane, the weight advantage of the plastic glass pane bringing clear advantages, as well as excellent splinter protection of the plastic glass pane made of Polycarbonate (PC) or another transparent plastic, such as polymethyl methacrylate (PMMA) or polyethylene (PE), the glass layers applied inside and outside the plastic glass pane when using windshield wipers or aggressive chemical cleaning agents from the inside or outside of a vehicle protect here.
Bevorzugterweise kann eine solche erfinderische Kunststoffglasscheibe auch als leichte und medienbeständige Schutzscheibe für Werkzeugmaschinen oder auch als leichte Schutzplatte für Forstfahrzeuge ausgebildet sein, wobei das geringe Eigengewicht die Handhabbarkeit drastisch verbessert und auch die Befestigungs- und Bewegungsbeschläge wesentlich graziler und damit auch wirtschaftlicher ausgeführt werden können, als sie es bei schwereren Glasscheiben sein müssen..Preferably, such an inventive plastic glass pane can also be designed as a light and media-resistant protective pane for machine tools or as a light protective plate for forest vehicles, the low weight drastically improving the manageability and the fastening and movement fittings being made much more delicate and thus also more economical than they have to be with heavier panes of glass ..
Entsprechend einer weiteren vorteilhaften Ausgestaltung der Erfindung kann die Schutzschicht auch aus zwei oder mehreren übereinander angeordneten Glasschichten bestehen, um deren mechanische Sicherheit und Widerstandfähigkeit weiter zu steigern.According to a further advantageous embodiment of the invention, the protective layer can also consist of two or more glass layers arranged one above the other in order to further increase their mechanical security and resistance.
Die durchsichtige Glasschicht weist vorteilhafterweise eine Dicke von nur 0,05 mm bis 2 mm auf, beziehungsweise, wenn sie aus einem ultradünnen Glas als Panzerglasfolie ausgebildet ist, nur bis zu 0,35 mm, so dass sie insgesamt sehr leicht und flexibel, aber dabei formstabil ist und trotzdem eine hervorragende Oberflächenqualität liefert, die dauerhaft kratzbeständig sowie widerstandsfähig gegen chemische Angriffe ist und damit insgesamt alterungsbeständiger, wobei auch Spannungsrisse von ansonsten oftmals zum Schutz weicher Kunststoffscheiben angewandter Hardcoatbeschichtungen vermieden werden können.The transparent glass layer advantageously has a thickness of only 0.05 mm to 2 mm, or, if it is formed from an ultra-thin glass as a bulletproof glass film, only up to 0.35 mm, so that it is overall very light and flexible, but at the same time is dimensionally stable and still provides an excellent surface quality that is permanently scratch-resistant and resistant to chemical attack and thus more resistant to aging overall, whereby stress cracks in hardcoat coatings that are otherwise often used to protect soft plastic panes can be avoided.
Die Schutzschicht aus ultradünnem Glas wird bevorzugt mit einer Klebeschicht auf die Kunststoffglasscheibe aufgebracht, die aus einer Optical-Clear-Adhesive-Folie, kurz OCA-Folie bestehen kann, die eine Dicke von nur 0,05 mm bis hin zu 5 mm aufweisen kann, wobei die OCA-Folie aus einer thermoplastischen Polyurethan-Folie, kurz TPU-Folie, bestehen kann.The protective layer made of ultra-thin glass is preferably applied to the plastic glass pane with an adhesive layer, which can consist of an optical clear adhesive film, OCA film for short, which can have a thickness of only 0.05 mm up to 5 mm, whereby the OCA film can consist of a thermoplastic polyurethane film, or TPU film for short.
Entsprechend einer anderen Ausführungsform der Erfindung ist die Schutzschicht mit einer Kleberschicht auf die Kunststoffglasscheibe aufgebracht, die aus einem Liquid-Optical-Clear-Adhesive-Flüssigkleber, kurz LOCA-Flüssigkleber, besteht, der üblicherweise eine UV-härtende PU-, Acryl- oder Silikonbasis besitzt.According to another embodiment of the invention, the protective layer is applied to the plastic glass pane with an adhesive layer which consists of a Liquid Optical Clear Adhesive adhesive, LOCA for short, which is usually a UV-curing PU, acrylic or silicone base owns.
